Description

Technical Field

[0001] The utility model belongs to the technical field of condenser production, and particularly relates to an assembly structure of a heat exchanger. Background Art

[0002] A condenser is a component of a refrigeration system and belongs to a type of heat exchanger. It can convert a gas or vapor into a liquid and transfer the heat in the tube to the air near the tube in a very fast manner. The production of a condenser is a complex and precise process, involving various materials, processes, and equipment configurations. The main raw materials include aluminum foil rolls, copper tubes, etc. Aluminum foil is used to make fins to enhance the heat dissipation effect of the condenser by increasing the heat exchange area. Copper tubes are widely used in the heat exchange pipes of condensers due to their excellent heat conduction performance.

[0003] In the existing heat exchanger assembly structure, the heat exchange copper tubes are sequentially passed through the fins and the tube sheet, and a U-shaped tube is sleeved on the interface end of the heat exchange tube, and then welded and fixed. However, since the outer shapes of the interface ends of the heat exchange tubes are the same and arranged neatly, it is not easy to distinguish. When sleeving the U-shaped tube, if the proficiency is not high, the U-shaped tube may be sleeved on the wrong interface, resulting in rework. Moreover, during the process of transporting the sleeved U-shaped tube to be welded, the U-shaped tube often falls off. Content of the Utility Model

[0004] The purpose of the utility model is to provide an assembly structure of a heat exchanger. By inserting the heat exchange tube to drive the support rod to rotate, the pointing rod rotates, marking the two interface ends that should be sleeved with each other, providing a standard for the subsequent sleeving of the U-shaped tube, preventing the U-shaped tube from being sleeved on the wrong interface and causing rework, enabling the sleeving of the U-shaped tube and the interface end of the heat exchange tube to be more firm, avoiding the U-shaped tube from falling off during the transportation process, and improving the work efficiency of the whole structure, which is more time-saving and labor-saving.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] An assembly structure of a heat exchanger, including a condenser. One side of the condenser is fixedly assembled with a tube sheet. Both ends of the outer wall of the tube sheet are provided with grooves. The middle of the groove is rotatably connected with a rotating block. The outer wall of the rotating block is symmetrically and fixedly connected with pointing rods. A rotating shaft is rotatably connected inside the tube sheet. One end of the rotating shaft is fixedly connected with a bevel gear one. One end of the rotating block and inside the tube sheet is fixedly connected with a bevel gear two. The bevel gear two is meshed with the bevel gear one. A rotating groove is penetrated and opened between two tube holes at both ends of the tube sheet. The top of the rotating shaft and inside the rotating groove is symmetrically and fixedly connected with support rods. The inner wall of the rotating groove is fixedly connected with a bending spring. The bending spring is fixedly connected with the rotating shaft through a connecting plate at one end.

[0007] A number of heat exchange tubes are assembled inside the condenser in a movable manner, and tube holes for the heat exchange tubes to penetrate are equidistantly perforated through the middle of the tube sheet.

[0008] One end of the heat exchange tube is sleeved with a U-shaped tube in a staggered manner on one side of the tube sheet, and a cross plate is fixedly connected to the outer wall of the tube sheet on the outer side of the rotating block.

[0009] A fitting rod is fixedly connected to the bent part of the U-shaped tube, and dividing rods are symmetrically fixedly connected to one end of the fitting rod.

[0010] A tapered head is fixedly connected to one end of the dividing rod, a through slot is arranged between the two dividing rods, and embedding slots for the dividing rods to be embedded are equidistantly perforated through the middle of the cross plate.

[0011] The technical effect achieved by the present utility model is that: the rotation of the support rod is driven by the insertion of the heat exchange tube, so that the pointing rod rotates, marking two interface ends that should be sleeved with each other, providing a standard for the subsequent sleeving of the U-shaped tube, preventing the U-shaped tube from being sleeved with the wrong interface and causing rework, enabling the sleeving of the U-shaped tube and the interface end of the heat exchange tube to be more firm, avoiding the U-shaped tube falling off during handling, and the whole structure improves the working efficiency and is relatively time-saving and labor-saving.

[0020] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation modes of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0021] As Figure 1 , Figure 3 , Figures 5-6 shown, a heat exchanger assembly structure includes a condenser 1. A number of heat exchange tubes 120 are movably assembled inside the condenser 1. A tube sheet 101 is fixedly assembled on one side of the condenser 1. Tube holes 111 for the heat exchange tubes 120 to pass through are equidistantly formed through the middle of the tube sheet 101. Grooves 108 are formed at both ends of the outer wall of the tube sheet 101. A rotating block 109 is rotatably connected to the middle of the groove 108. Pointing rods 110 are symmetrically and fixedly connected to the outer wall of the rotating block 109. A rotating shaft 113 is rotatably connected inside the tube sheet 101. A first bevel gear 115 is fixedly connected to one end of the rotating shaft 113. A second bevel gear 119 is fixedly connected to one end of the rotating block 109 and located inside the tube sheet 101. The second bevel gear 119 is meshed with the first bevel gear 115. A rotating groove 118 is formed through between two tube holes 111 at both ends of the tube sheet 101. Support rods 114 are symmetrically and fixedly connected to the top of the rotating shaft 113 and located inside the rotating groove 118. A bending spring 117 is fixedly connected to the inner wall of the rotating groove 118. The bending spring 117 is fixedly connected to the rotating shaft 113 through a connecting plate 116 at one end.

[0022] According to the above structure, the heat exchange tube 120 is inserted into the condenser 1 from the end with the groove 108. When the heat exchange tube 120 passes through the tube hole 111, it will push the support rod 114 until one end of the support rod 114 is flush with the opening of the rotating groove 118. The heat exchange tube 120 passes through the tube sheet 101. The support rod 114 drives the rotating shaft 113 to rotate, and the bending spring 117 contracts accordingly. The rotating shaft 113 drives the first bevel gear 115 and the second bevel gear 119 to rotate together. The second bevel gear 119 drives the rotating block 109 to rotate, and the rotating block 109 drives the pointing rod 110 to rotate, so that the pointing rod 110 points to the interface ends of two heat exchange tubes 120 that are diagonally distributed at this time.

[0023] Refer to the attached Figures 1-3 、 Figure 5 At one end of the heat exchange tube 120 and on one side of the tube sheet 101, U-shaped tubes 102 are sleeved in a staggered manner. On the outer wall of the tube sheet 101 and outside the rotating block 109, a cross plate 103 is fixedly connected. At the bent part of the U-shaped tube 102, an inserting rod 104 is fixedly connected. At one end of the inserting rod 104, separating rods 105 are symmetrically fixedly connected. At one end of the separating rods 105, a conical head 107 is fixedly connected. A through groove 106 is arranged between the two separating rods 105. At the middle part of the cross plate 103, inserting grooves 112 for the separating rods 105 to be inserted are equidistantly penetrated and opened.

[0024] According to the above structure, the U-shaped tube 102 is sleeved on the interface end of the heat exchange tube 120 according to the direction indicated by the pointing rod 110. Slightly pinch the two separating rods 105 to make them contract. After the separating rods 105 and the conical head 107 pass through the inserting grooves 112, release the separating rods 105. The conical head 107 rebounds due to the loss of external force and thus gets stuck on one side of the cross plate 103, preventing the U-shaped tube 102 from falling off. In the utility model, the insertion of the heat exchange tube 120 drives the support rod 114 to rotate, so that the pointing rod 110 rotates, marking the two interface ends that should be sleeved with each other, providing a standard for the subsequent sleeving of the U-shaped tube 102, preventing the U-shaped tube 102 from being sleeved on the wrong interface and causing rework, enabling the sleeving of the U-shaped tube 102 and the interface end of the heat exchange tube 120 to be more firm, avoiding the U-shaped tube 102 from falling off during the handling process, and the whole structure improves the work efficiency and is relatively time-saving and labor-saving.

[0025] The working principle of the utility model is as follows: Insert the heat exchange tube 120 into the condenser 1 from the end with the groove 108. When the heat exchange tube 120 passes through the tube hole 111, it will push the support rod 114 until one end of the support rod 114 is flush with the opening of the rotating groove 118. The heat exchange tube 120 passes through the tube sheet 101. The support rod 114 drives the rotating shaft 113 to rotate, and the bending spring 117 contracts accordingly. The rotating shaft 113 drives the bevel gear one 115 and the bevel gear two 119 to rotate together. The bevel gear two 119 drives the rotating block 109 to rotate. The rotating block 109 drives the pointing rod 110 to rotate, so that the pointing rod 110 points to the two interface ends of the heat exchange tubes 120 that are diagonally distributed at this time. Sleeve the U-shaped tube 102 on the interface end of the heat exchange tube 120 according to the direction indicated by the pointing rod 110. Slightly pinch the two separating rods 105 to make them contract. After the separating rods 105 and the conical head 107 pass through the inserting grooves 112, release the separating rods 105. The conical head 107 rebounds due to the loss of external force and thus gets stuck on one side of the cross plate 103, preventing the U-shaped tube 102 from falling off.

[0026] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented by conventional means in the art without special explanation and limitation.
